[tammoon]

I was denied efile and I mailed in a paper return how long does that take to accept or deny

Check the IRS site 4 weeks after you mail the return however the return can take longer to show up and 6 weeks or more to process ... https://www.irs.gov/refunds

Hopefully you used some kind of tracking on the mailed in return so you know they at least got it.
